To all whom it may concern:

Be it known that l, WiL IAM' A. Md ADAMS, a citizen of the UnitedStates, and resident of Bay Shore, in the county of Suffolk and State ofNew York, have invented a new and useful Aluminum Alloy, of which thefollowing is a specification.

My invention relates to an aluminum alloy, with the object in view ofproviding a silvery White metal capable of being rolled, hammered,machined and otherwise worked as a malleable metal for general use inthe arts.

With the foregoing object in View, my invention consists of an alloycomposed of tin, silver, cadmium and aluminum combined in substantiallythe following proportions, to wit: tin, eight per cent. by weight;silver four per cent. by weight; cadmium eight per cent. by weight; andaluminum eighty per cent. by weight. In combining these substances toform the alloy, 1 first melt a portion of the aluminum, for exampleone-third, and raise it to such atemperature that the silver, whenintroduced, will readily com bine with it. The silver is then introducedand after it has combined with this portion of the aluminum, theremainder of the aluminum is introduced into the mass, such introduction materially lowering the temperature of the mass. The cadmiumis then lll' troduced and then the tin, or the tin may be Specificationof Letters Iatent.

of introduction of these two substances being; a matter of choice orconvenience. It is to be understood that the mass is to be thor-- oughlyagitated when the different elements are introduced in order to make themass homogeneous and thoroughly min the solostance being introducedthroughout the U'IHSS into which it is introduced. The mass is thenskimmed to remove any flux which may have been employed and then it maybe poured to form ingots of any desired shape. These ingots are of amalleable nature and may be treated as a malleable metal and will have abrightness substantially like that oft unoiiidized silver. This metalwill retain its luster and is proof aga inst disintegration by It isextremely ductile and amply strong for the manufacture of all silverwareand may be furnished at a cost far below the cost of silver.

What I claim is:

An aluminum allo com weed of tin silver, cadmium and aluminum in theor-open trons substantially as set forth.
